  1. ClockAide Anita Ganesan, Eric Moore, Sachin Honnudike, Joel Jean-Claude

  2. Outline • Project Overview • Requirements Overview • Demonstration – Main System • Components Overview • Challenges • Budget • Demonstration – Additional functionality

  3. Project Overview • ClockAide is an educational tool for special needs students in West Springfield • Students of varying skill level will use our device to learn how to Set and Read an analog clock

  4. Requirements • Device will speak and display the current time to user when prompted • Device will allow user to practice reading time • Device will allow user to practice setting time • Device will allow users lacking fine motor skills to turn knobs for easy setting of the hands • Device size will not obstruct the normal use of the classroom and be approximately the size of a students' desk

  5. Demonstration • Normal Mode • User Identification • Set Mode • Read Mode

  6. Components Overview • Power Source • ATX Power Source • Breakout Board • Raspberry Pi • Stepper Motors • Arduino Microcontroller • Coaxial shaft for hour and minute hand representation • Keypad • Arduino Microcontroller • Reverse engineered keypad matrix • Serial controlled 16x2 LCD screen • Casing • Dual coloured acrylic sheets

  7. Components – Raspberry Pi • Implemented a finite state machine for control of ClockAide • Real Time Clock for system time • Coding done in Python • Implemented Serial Communication interface for communication with motor and keypad microcontrollers • Determined logic to correctly select and play the appropriate sound sample for user prompt

  8. Components – Mechanical Drive System • Stepper Motors • Arduino Microcontroller • Coaxial gear driven shaft • Hand and Minute Representation

  9. Components - Keypad • Arduino Pro • Reverse engineered the keymap matrix • Serial LCD Screen

  10. Components – Power Source • ATX Power source • INPUT: 100-127V /6A • 200-240VAC/3A 50/60 Hz • Output: +5VDC / 20A MAX +3.3VDC / 17A MAX +12VDC / 15A MAX • ATX Breakout board • Output: +5VDC +3.3VDC +12VDC

  11. Components – Casing • Dual colored acrylic sheets representing W. Springfield Middle School colors • Extensive machine shop work to cut sheets into desired shapes • Integrated Speakers • Built shelf for part placement • Size of a students’ desk

  12. Challenges • Integration • Robust communication between Raspberry Pi and peripherals • Keypad • Stepper motors • Raspberry Pi was continuously resetting – challenge at CDR (fixed) • Arduino processing time • Encoders Broken – Set mode • Feedback will be integrated in time for delivery – end of May

  13. Updated Cost

  14. Deliverables • Feedback system • Implemented not integrated • CSV file to excel for accessing data • Set Time feature • PCB

  15. Demonstration • Feedback System • CSV
